Zdravim,

resim divnou zalezitost pri prijovani PDA (Dell Axim X30) v USB kolebce. V momentu kdy dam PDA do kolebky, kernel spravne detekuje zarizeni a hotplug spravne natahne potrebne moduly. Ale pak asi po 5ti vterinach ze zarizeni samo odpoji. Hned po odpojeni se zase detekuje, ze je zarizeni pripojene. A tohle porad dokola .... viz nasledujici log (a log s debugovanim usb na konci):

Tuhle chybu ale dela pouze to pripojovani PDA, ostatni USB zarizeni, co byly kdy pripojeny (hard disk, flash disky, mys, bluetooth modul), fungovaly bez problemu?!

Mam kernel 2.6.13 s Gentoo patchi (ale zkouseno i na 2.6.12). USB je:

0000:00:10.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 80)
0000:00:10.3 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 82)

Stalo se vam to nekomu ? Poradilo se to vyresit ? Nebo alespon kudy patrat ... chyba USB v kernelu, driveru ipaq, hardwarova chyba ...

Diky za info.

Ch.
